They aren't directional - if you look at the sidewalls it says "outside" on the er outside sidewall, this is to give more tread to the outer edges for cornering
Does Anyone Understand Tread Patterns
Evening all,
It's been a while since I have posted but I am hoping a few of the sites oracles can explain the tread pattern on the Goodyear Eagle F1 Asymmetrics. I need 4 new tyres and after running two of these on the front I am incredibly impressed and was about to buy a set of four.
However, I am confused about how the tyres which will be fit to the left side of the car can be doing the same job as the ones on the right as the asymmetric pattern will be running backwards (the tyres are not directional and don't have a different tyre for left and right).
I guess I should just be happy that they work - but I prefer to understand what's going on

Here are a couple of images of the tyres as they will be fit and you can see the patters are reversed. This would be front left & front right as looking from the front of the car.

You would expect that if the tyre on the right (above) is designed to expel water, then running backwards as the one on the left would be, it wouldn't be very efficient at expelling water???
You would expect the tyres to look like this from the front:

Here is a thread where someone else is discussing the exact same thing (where I pinched the images).

Anyway, if anyone can shed some light on it, it would be hugely appreciated

lol - thanks robbyvrs.
I think you missed the point somewhat

. I know they are not directional, the point of an asymmetric tyre is that one wall is specifially designated as the outside wall and that wall is typically stronger with less groves providing better cornering grip. But some asymmetric tyres are also directional so that the tyre pattern runs the same way - so you have a left and right style of tyre.
The F1 eagle asymmetric are not directional - only asymmetric which confuses me how the tread pattern can do its job of expelling water while effectively running backwards.
Cheers anyway

well some tyre manufacturers sell right + left handed tyres - and usually 1 side is dearer than the other
